Dr John Collier, headmaster at St Andrew's Cathedral School in Sydney, expressed his displeasure in a recent newsletter, over the increasing number of incidents involving “unrestrained” attacks on teachers by parents.

According to The Australian, Collier said, “I am having to interact with too many parents who have verbally abused, physically threatened or shouted at a staff member”.

It is reported Collier also warned that the high fees parents pay to the school do not give them the right to treat staff like servants. 

“I am aware some parents, because they are paying fees, see the relationship with teachers as a master/servant relationship, such that they are entitled to make extravagant demands,” he said in the newsletter.

Collier told such parents to "chill", and warned they may be banned from entering the school grounds if such behaviour was to continue.
